Cat with cancer only eats tuna. What diet or supplements are best?

Thanks for using Petco Pet Education Center, formerly Petcoach! I am sorry he was diagnosed with this tumor. This is unfortunately a very aggressive cancer. If he is going to just be on palliative care at this point then the focus would be more on making sure that he is comfortable and eating and feeling well. Prednisolone is a good idea. Another medication that just came out in the market is Entyce which is an appetite stimulant that I have been using in cancer patients which may improve his appetite. At this point you can feed him whatever he prefers though something that is tasty and they tend to like is canned tuna so you can try that. The Entyce has worked great for my cancer patients so far and he may have a better appetite afterwards. Also, an anti-nausea medication like ondansetron. Your veterinarian could prescribe these if that would be ok with his medical history. Good luck!

I'm so sorry to hear that Elliot has cancer. You are exactly right that the most important thing is for Elliot to keep eating. I don't have any fool proof recommendations, but my cats really liked Tiki Cat and Wellness canned food. Some cats will also like variety, so you might rotate flavors. Good luck! I hope that was helpful. Thanks for using Petco Pet Education Center, formerly Petcoach.

They make cancer specific diets such as science diet N/D. The problem is when you have cancer, the cancer cells steal the nutrients that their body needs and that helps it replicate, so you are essentially feeding the cancer. The main goal is the keep a good appetite and use small frequent meals

I'm so sorry that Katie was diagnosed with lymphoma. Athough they have not done as significant of studies in cats as they have with dogs, our goals with cancer are to feed a food high in protein and fat, but low in carbohydrates. This is especially important for cats since they are obligate carnivores, so a canned food is ideal. A salmon based diet is a wonderful idea since omega 3 fatty acids can have some anti-cancer effects. My cats love Blue Buffalo Wilderness Salmon. They also love Wellness Turkey and Salmon. Cats rely on their sense of smell to entice their appetite, so smelly fish based foods are a great idea for a cat with cachexia. I also find that rotating foods on a regular basis can be very useful for cats on chemo, so they don't get turned off to a particular food if they are nauseated. I hope that was helpful!

I am sorry to hear about your kitty! A decrease in appetite is not unusual in cases of cats with cancers and on certain medications. Definitely keep your vet in the loop about where her appetite stands/how she is doing eating as they may want to adjust/add medications. This article gives information/ideas on this issue: https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4952607 In some cases we do end up placing feeding tubes to provide nutrition if needed. Some cats enjoy the food warmed up, so you can try warming it in the microwave (always check temperature before feeding to ensure not too hot). Some prefer wet food, some kibble, some like kibble that has been soaked to soften it. Trying a buffet to give varieties to choose from may help you discover what she finds appealing.

I recommend feeding Hills a/d. It’s easily digestible, cats usually love it and it is very calorie dense so Watson will start to recover quickly even if he doesn’t eat that much. I would also have a dry kitten food available at all times and offer some tasty cat treats to stimulate his appetite. In addition to feeding many meals daily increasing his exercise will help build muscle and also stimulate his appetite and speed his recovery.

Oh dear, I'm sorry to hear that you and Bonnie are in this situation. Bonnie's weight loss could be caused both by her lack of appetite, as well as any cancerous process and/or subsequent kidney disease. You can try to tempt her to eat with bits of boiled white meat chicken, small amounts of tuna, or even meat-based baby foods. Also discuss appetite stimulant medications (cyproheptadine and mirtazepine are two commonly used drugs) with Bonnie's veterinarian since they may be helpful. However, if none of these strategies improve her appetite and her overall quality of life is declining, it may be time to consider euthanasia. I hope this helps and that all goes well for Bonnie.
